SPRING FAN.' APPL'IOATION FILED APB.. 27, 1909.

'INVENTOR To all whom it may concern.:

Beit known that L'DARio RonER'rI, a 4subject'of the King of Italy,residing at New-` ark, .in the county of Essex and 'State oi -NewJersey,have invented certain new and `useful improvements 1n Spring-Fans; and

l `do hereby'declare the following to be a full, clean,- and.` vexactdescription of the invention', such as will enable others 'skilledinv-the' art to Kwhich it appertains tomake andu'se the'same, referencebeing had to the accompanying drawings, and to figures ofreferencehmaa'ked thereonwhich form a part oli this specification.

This invention relates to an improved fans, and particularly to aportable fan that isinounted on a standard and has a rotating iconsisting of blades, the pitch of the bladesbeing adjustable so thatthe force of thefcurrent of vair being propelled can be i regulated.

The invention is further designed to provide a fan that is operatedfromA a spring motoreuid is 'provided with a brake attach-` nient" so;that the speed of the fan can be 4 regulated. v still*further,improvement consists in thexfiiountilng of the fan and itscasing on a. Vstandard so that it rests thereon. 1n a fixed. position',or it can be arranged to rotate .stead-'lily i-n a certain direction todis- .tribiitetheair to: better advantage, the rotaining apparatus beingactuated by the same springer lsprings that-actuate the fan blades.

Theldeviee alsoicormprises a music-box attachment-'which canjbe -placedin or out of z-perai'fivel connection with a mech anism for propelling lthe y fan.'

.'llieinvention is' illustrated in the accompanyiing drawings, in.which- Figune "1v is'af face view o l" the fan with and its standard.,showing the casing in section.` iFig. wis afrearview of the devicewith-the casi-ng broken away, and Fig. l is a verti'cahcentralf sectionthrough the spring and'thetransinission'gearing. Figa 5y is a. detailvi`evvf oit' thehub ofthe fan and the methodof attachingy the blades.

The device consists oga 'hollow' standard .1-0- which can be of anyusual configuration and is provided .with a centrally arranged rod 11which is rotatably -mounted in the standard and also '..lnovable`longitudinally therein as will be, described hereinafter, a1-

though the longitudinal movement is not necessary where the fan is to bemade fixed to the standard. Mounted on top of the rod 11 is a casing` 12having a bottom 13 To the top of the rod 11 isl secured a block 14 fromwhich eX'- tend. the uprigh'ts 15 and 1G which extend upwardly andbetween which are mounted the springs 17, which springs have one end,-

'as 18, of each one secured to theuprights, the other end of each springbeing.' secured as in Fig.` t, or any other suitable Way, to a sleeve 19which is arranged to rotate on the shaft 20, the shaft 20 bei-ng heldagainst rotation by a squared or rectangular portion 21,011 the fron-tend, which fits in the up- I right 16.

The usual ratchet 22 is secured to the end ofthe sleeve 19 to hold itagainst unwinding, except with the gear 23 to which the ratchet 22isfastened, the pa wl Q4 (co-acting. with the ratchet, being normallyheld down by the spring 25. Secured by al screw 26 tothe upright 15 is abracket 27 which is provided with a rotatable shaft Q8 having.projections to fit in the recesses in the shaft 20 or. 'any4 otherdetachable operative connection which is operated from the gear 29 whichin turn is turned byv a gear 30, the shaft of which has a squaredportion 3l to receive a lever 32 of the handle 33 so that the spring'-or springs, if more than one is placed in para-lilel relation, can bewound.

lt'otatably arranged on the rod. Iifl is a sleeve 35 on which is.secured a. gear 36 wuirii meshes with the gear 22K, and on the outerend of the sleeve is placed a. large gear 37, the shaft exteiidingbeyond the gear and being mounted in a plate 38 which is fastened by anysuitable means to the upright 16.' This train of kiggearing that hasbeen described and the description of which will be continued isdesigned to increase the revolutions. The gear 3T meshes with a. gear 3Swhich is mounted on the same stud 3921s a larger gear 40. The largergrai- 40 meshes With twosinaller gears'll and l2 which are mountedslightly below and on each side of thev center of the gear 40,. thesegears rorespectively, which both' mesh with a smaller ies' gea1-45 which1s mounted on a small shaft .457 beit, t fastened to the shaft 4S whichis the'sha on `whicl1the tan ismountod. The

shaft [t8 rotates in a tubular bearing 49' -tened by a suitableset-screw 53, holding the shaft in place and also acting to hold thefan, sinceit is integral or secured to a disk t which is adjustabletoward and from a disk by means of the screws The blades 57 are providedwith studs 58 which tit in the recesses inthe opposed faces of the disks54 and 55 and can be fastened at a desired angle, but when the screws.36 are nnloosened they can be turned so that the pitch can beregulated. A frame 59 is suitably' fastened to the front of the casingl2 and has the arms 60 to protect the fan blades from damage and anunwary person from injury. These arms are joined by a disk Gl to whichis secured a hollow. cap (S2 in which is slidably arranged a rod 63which has a head G4 thereon, the head being recessed as at 65 to receive.the pointed end 66 of the shaft 48.

A spring 67 pushes against the collar 68 having one end abutting thereonand having thev other end abutting against the disk 61 so that the head(54 is normally pulled away from the end of the shaft 4S, but a screw 69can be used to force the rod (53 against the action of the spring, and abraking action can be put on the shaft t8 to regulate the speed of thefan. The gear 23 meshes near the bottom of the casing with a. smallergear- 'wheel 70 which is mounted on the shaft 7l and is provided with abeveled gear 73. he beveled gear 73 meshes with a fixed beveled rack 74of a circular form which supports a disk 72and' between this disk 72anda plate 75 on the bottom of the casing are the balls 7G which form aball-bearing. lVhen the sprii'ig is wound up the fan can be held againstrotation by the brake being placed in engagement with its shaft, andafter the spring is wound the brake can be released and the transmissiongears between the spring and its shaft and the fan and its shaft willcause a rotation of the fan for a long time at a high speed with aslight relaxation of the spring.

Then the fan rotates the gear 73 rotates to vary its speed. a spring tonorn'ially withalso on account of its connection with the l shaft of thespring, and engaging the circular rack on the standard it causes thecasing to revolve on the standard so that l the current of air isdistributed around a room or in the vicinit)v of where. the fan isplaced. To prevent the rotation of the casing the shaft l1 can be raisedby the. lever 77 which is pivoted intermediate of its ends at 'T8 to theinside of the casing, and which has its end `opposite the oneengaging'i'the bot-tom of the rod 1 1 adapted to be forced downward bythe stud T9 on. which the linger-piece 80 is arranged. lVhen thefinger-piece S0 and its stud TE) are forced down the rod' ll is shovedup so that the gear T23 is discoi'mectcd from the rack T4. 'the stud T5)slides in a thimblc Sl which has a recess S2, and a pin 83 passingthrough the stud tits in the recess 82, when the casing is down andadapted to be rotated, but

when the ngenpiece 80 and its 'stud 79 are pushed down to raise the rodil, the linger-piece is slightly turned and the pin 83 is placed at anangle to the recess 82 and the rod 1l, and the easing with its fan isprevented against descending and thus stands rigid in any position it.is placed, but it can be rotated easily by hand to adapt it. forthrowing the air current. in any desired direction.

,lf desired, a musical attachment can be provided which consists of aframe 84: having the ordinary roll'S therein which e11- gages with aseries of spring forks or strips, the frame being n'iounted pivotally ona rod 86.

The device is operated by a gear meshing with the gear il() of thedriving mechanism and is actuated, that is, the gear 90 is held into orout of mesh with the gear 3G by a. handle 8T which has a linger 88 whichis adapted to tit in the holes Si) in the back of the casing l2, as willbe seen from Figs. 2 and 3.

A fan comprising a standard, a casing on the standard, a spring motorin the casing, a fan mounted on the front of the casing, means foroperating the fan from the spring motor, a guard surrounding the fan,and an adjustable brake mounted in the guard and adapted to bear on theend of the fan for aeving its speed.
